Flood zones and zoning in Puerto Rico

The Land and zoning part puts together what people ask most before buying a lot or a house.

• The flood zone from the official flood maps, and the advisory flood zone drawn after Hurricane María.
• The zoning, and whether the lot is in a historic zone or a protected karst area.
• Landslide risk, liquefaction risk, the tsunami zone and coastal erosion.
• Permit cases near the property in the last 12 months.
• The area's income.

In Map View, Map layers turns on the flood zones. Both flood maps are joined in one, and where they overlap the map shows the higher level.

The colors tell the risk, from coastal with waves to high risk (1% a year) and moderate (0.2% a year).

A flood zone can raise the cost of insurance and change what can be built. The zoning tells what uses the land allows.

These facts come from public maps and can be out of date. For an important decision, confirm them with a surveyor, an engineer or the permits office.
